沪外教英语八上Unit7语法讲解及习题 复合不定代词（some/any + nouns） 一、语法核心讲解 （一）复合不定代词的构成 由 some/any/no/every + thing/one/body 构成，指代“人/物/事”，是本单元核心语法点： 前缀 + thing（事物） + one/body（人） some something someone / somebody any anything anyone / anybody no nothing no-one / nobody every everything everyone / everybody （二）核心用法规则 1. some- 与 any- 的基本区别 · some-：多用于肯定句，表“某事/某人/某物”； 也可用于期待肯定回答的疑问句或提出请求/邀请。 例：People learned something new. 例：Would you like something to drink? · any-：多用于否定句和疑问句，表“任何事/任何人/任何物”； 也可用于肯定句表“几乎所有”。 例：Don’t tell anybody about it. 例：Anybody can learn this skill. 2. no- 与 every- 的用法 · no-：表“没有任何事/人”，本身含否定含义。 例：Nothing beats real mail. 例：Nobody knows the answer. · every-：表“所有事/所有人”，强调整体。 例：Everything is ready. 例：Everyone likes this idea. 3. 形容词后置规则 修饰复合不定代词的形容词，必须放在代词之后： ❌ 错误：interesting something ✅ 正确：something interesting 例：I have something important to tell you. （三）核心对比表 类型 用法场景 示例 some- 肯定句/期待肯定回答的问句/邀请 People learned something new. any- 否定句/疑问句/肯定句表“几乎所有” Don’t tell anybody about it. no- 表否定“没有” Nothing beats the real mail. every- 表“所有/全部” We can buy almost everything online. 形容词后置 修饰代词时形容词放后面 something new, anybody creative 2、 习题 题型1：单项选择 1.
